The value of object 0x6407:01 CO Decimal digits current value / set point is determined and optimized
automatically during instrument power-up.
5 Examples:
fMeasure = 1.15 ln/min
object 0x6407:01 CO Decimal digits current value / set point = 3
object 0x7401:01 CO Effective current value Xeff = 1.15 x (10 x 10 x 10) = 1150
object 0x6407:01 CO Decimal digits current value / set point = 4
object 0x7402:01 CO Setpoint W (INT) = 22500
fSetpoint = 22500 / (10 x 10 x 10 x 10) = 2.25 ln/min
3 Integer16 value scaled with the value of object 0x6407:01
5 Integer16 value scaled with the value of object 0x6407:01
